FlLLlNG-REPLENISHING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 725,790, dated April21, 1903.

Application filed February 2, 1903. Serial No. 141,515. (No model.)

' a citizen of the United States, and a resident of l'lopedale, countyof Worcester, State of Massachusetts, have invented an Improvement inFilling-Replenishing Mechanism-for Looms, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like characters on the drawings representing like parts.

This invention relates to that type of filling-replenishing loom whereinthe filling-supplies are held in a movable feeder which is movedintermittingly to bring the filling-sup-- plies one by oneinto positionto be transferred to the running shuttle. Various means have beendevised for effecting the movement of the feeler, such as by anintermittinglywound spring in United States Patent No. 529,940, thestoppage of such movement being effected through the filling-supply nextto be removed. Following this apparatus other means were devised, as inUnited States PatentNo. 651,715, where a light spring started themovement and the transferrer completed it, and later a pawl on thetransferrer moved the feeder, as in United States Patent No. 66ai,790,the stoppage of the feeder being effected by the impact of the endmostfilling-supply against a fixed stop. Still later, PatentNo. 710,023disclosed means to positively lock the feeder between successivetransferring operations, initiated the advance of the feeder by a lightspring rendered active by operative movement of the transferrer, andcompleted the movement of the feeder positively as the transferrerresumed its normal position, stopping the feeder independently of thefilling-supplies. Such feeder actuation is effective and overcomes theobjectionable feature of stopping the feeder byor through afilling-supply.

My present invention also provides for a positive and definite stoppageof the filling feeder or holder independently of the fillingcarriers,advances the feeder positively, and retains it locked under normalcircumstances. I have, however, eliminated altogether the light springreferred to in the patent last ever, to prevent retrograde movement ofthe feeder when unlocked and during-the operative movement of thetransferrer, so that no jarring or vibration of the loom can have anyimproper effect upon the. feeder.

The construction is very simple, the operation direct, positive, andaccurate, and each transferring operation causes a definite ad- Vancemovement of the filling feeder or holder.

' The various novel features of my invention Will be describedhereinafter in the subjoined specification, and particularly pointed outin the following claims.

Figure 1 is a transverse sectional View of a portion of a loom havingone embodiment of my invention applied thereto, taken through the axisand between the end plates or disks of the filling-feeder, thereplenishing mechanism being shown in normal position; and Fig. 2 is adetail of a part of the transferrer and the means for controlling thefeeder, the latter being shown unlocked as the transferrer operates.

The filling feeder or holder comprising two connected disks mountedrotatably on a stud a, projecting horizontally from a stand A on thebreast-beam A, the filling supplies or carriers I), supported by thedisks, one of which, as a, is herein shown, the transferrerf, fulcrumedon a fixed studfand adapted to re- No. 710,023 referred to, thetransferrer being returned to normal position by a spring S Fig. 1, inwell-known manner.

A toothed disk or ratchet-wheel a rotatable with the feeder and locatedat the inner side of disk a, has teeth which in practice correspond innumber to the holding devices for the filling-carriers, the latter beingshown in Fig. 1 as circularly arranged relatively to the axis of thefeeder.

The transferrerf has at its free end alateral projection f whichsupports a pawlcarrier fl fulcrumed on the transferrer at f and providedwith a pawl f which cooperates with the toothed disk a and in Fig. l thenormal position of the parts is shown, the transferrer being in itshighest position and the pawl in engagement with a tooth, as 6, of

the disk. At such time the pawl acts to prevent retrograde movement ofthe feeder unless force enough he used to flex the transferrer-spring Sand depress the transferrer. To prevent such forcible retrogression,however, I have provided a detent-pawl d, upturned and bent at its upperend to engage the disk 0. and enlarged at its lower end, as at (1', saidpawl having an elongated upright slot (1 to receive a stud a extendedlaterally from the stand A The heavy end of the detent-pawl normallymaintains it in the position shown in Fig. 1, said pawl having a tail (iwhich projects over and rests upon the hub of the transferrer.Manifestly any retrograde movement of the feeder will be resisted by thedetent-pawl, while upon the advance movement of the feeder the pawl willclick over the teeth of the disk a and fall into operative position whensuch movement ceases.

The transferrer has secured to or forming part of it at its free end anupturned dog f between the pawl-carrierf and the disk a and adapted toengage the toothed disk a when the transferrer is in normal position, asshown in Fig. 1.

At such time the rear face f of the dog engages or rests against theouter face of a tooth, as 3, of the disk at and manifestly at such timethe feeder cannot move forward. When the parts are in this position, thefeeder is locked, with a filling-carrier in position to be transferredat the next operation of the transferrer, such a filling-carrier beingindicated at b Fig. 1. When a filling-carrier is to be transferred tothe shu ttle, the transferrer is depressed to engage the endmostfilling-carrier of the series in well-known manner, and on suchoperative movement of the transferrer the dogf is withdrawn from thedisk a unlocking the feeder. At the same time the weight of thepawl-oarrierf causes it to follow the descent of the transferrer, whilethe pawl f clicks over the ratchet-teeth to be set in readiues for afresh hold.

By reference to Fig. 2 it will be seen that the pawl has left the tooth6 and has passed below the next tooth, as 5, in readiness to engage iton the next upward movement of the pawl, the faceof tooth 3 having beenlast engaged by the dog f prior to operative movement of thetransferrer. The fillingcarrier having been inserted in the shuttle, thetransferrer rises on its return movement, and the shelf or projection fpositively raises the pawl-carrier f, so that through engagement of thepawl f with tooth 5 the disk a and feeder will be advancel. Such advanceof the feeder will carry the tooth 3 to the left of the dog f before thelatter is elevated into its path, and as the transferrer reaches theposition shown in Fig. 1 the dog f will be in readiness to engage theface of the tooth 2 and positively stop the feeder. Thus the latter hasbeen advanced positively and stopped positively after a predeterminedadvance by the means described upon return movementof the transferrerand locked from movement when stopped, as hereinbefore pointed out.

The predetermined or definite advance movement-is of such extent thatthe next filling-carrier of the series in the feeder is brought intoaccurate position to be transferred; but while such filling-carrier willbe stopped adjacent or even in contact with the abutment h thefilling-carrier has no part whatever in stopping the feeder.

Should one or more of the holding devices of the feeder be empty, owingto carelessness or oversight in filling the feeder, then thehereinbefore-described operation will act to bring such'empty deviceinto position just as if a filling-carrier were present, there being nooverrunning of the feeder permitted or possible in the constructionherein illustrated, each definite advance of the feeder following anoperative movement of the transferrer.

Having fully described my invention,what I claim as new, and desire tosecure by Letters Patent, is-- 1. A movable fillingfeeder to holdaseries of filling-carriers, a transferrer, and means carried thereby tocooperate with and normally lock the feeder from movement and to releaseit upon operative movement of the transferrer, return movement of thelatteracting through said means to first advance the feeder positivelyand thereafter to stop and lock it when a predetermined advance has beeneffected.

2. A movable filling-feeder to hold a series of filling-carriers, atrausferrer, means carried thereby to cooperate with and normally lookthe feeder from movement and to release it upon operative movement ofthe transferrer, return movement of the latter acting through said meansto first advance the feeder positively and thereafter to stop and lockit when a predetermined advancehas been effected, and a separate deviceto prevent retrograde movement of the feeder when unlocked.
